The Bills practiced from 11 a.m. to 12:30 p.m. Thursday. Bills fullback Corey McIntyre, who missed most of Wednesday’s practice with a sore knee, took part in the workout.

“Corey did most everything,” Bills coach Chan Gailey said. “We’re going to list him as limited, but he did most everything and looked OK. I think he’ll be fine for Sunday.”

Cornerback Ron Brooks, who missed Wednesday due to a dental procedure, practiced and should be available Sunday, Gailey said.

The Colts are mostly healthy. Defensive end Cory Redding (hip), safety Antoine Bethea (ankle), cornerback Vontae Davis (knee) and tight end Coby Fleener (shoulder) all have been nursing injuries but all have a shot to play. Davis and Fleener have missed the past three games. Redding declared himself ready to play.

The Bills have been flagged for 14 and 11 penalties in the last two games, respectively. For the season, the Bills have 70 penalties for 573 yards. The penalty total is tied for 25th in the league (in terms of penalty avoidance). The yardage total is 19th. The league average is 64 penalties for 546 yards.

Gailey on the penalties: “I think there are a lot of little mistakes that we are making pre-snap that are hurting us right now. We have to avoid those pre-snap penalties. The post-snap penalties are going to happen. Most of those post-snap penalties in New England were pass interference, illegal contact or something like that. Then we had two or three of those the other day. A lot of these are pre-snap penalties that we just have to get more disciplined in our lines to eliminate that.”

Colts offensive coordinator and interim head coach Bruce Arians was fired by the Steelers after last season. Arians had served eight seasons with the Steelers and made three Super Bowl trips with the team.

Asked this week by Indianapolis reporters what he was particularly grateful for, Arians said: “I’m thankful for the Pittsburgh Steelers letting me go to be here. Truthfully, I couldn’t think of a better place to be at this point in time and to have felt more needed probably (than any time) in my entire life. So thank you, Pittsburgh.”

The Colts rank 14th in rushing, averaging 110 yards a game. Sharing the rushing duties are Vick Ballard, a fifth-round pick in April out of Mississippi State, and Donald Brown, a first-round pick from Connecticut in 2009.

“If you can run the ball well that sets up your play-action pass, which they love to do,” said Bills defensive end Chris Kelsay. “It gives (Andrew) Luck the chance to take shots down the field. So we need to shut down the run first and foremost and make them one dimensional. If we can do that then we can pin our ears back up front and hopefully force him into some bad throws, and put them on the ground a few times and see where we turn up.”
